bucket. Dumping receptacles of this land discharge through the bottom by gravity and the closure for the discharge opening must be of such a character that it will support the weight of the contents of the receptacle and can be opened and closed by the operator.

Hinged closures which open by gravity have not been found practical in dumping receptacles of this kind, particularly for handling concrete, and when a laterally movable or sliding closure is employed the weight of the material thereon, particularly in receptacles of large capacity, is such that the power required to open the same is often in excess of V the strength of one man.

One object of the present invention is to provide such a dumping receptacle having a laterally movable closure and operating means therefor which will enable the same to be easily opened.

A further object of the invention is to provide such a dumping receptacle with a swinging closure and an operating lever therefor which, when the closure is in its closed position, will be located alongside of and close to the receptacle where it will be out of the way and will not interfere with'the movements of the receptacle.

A further object of the invention is to provide such a receptacle which will be simple in its construction and of a strong durable character.

Other objects of the invention will appear as the device is described in detail.

In the accompanying drawing Fig. 1 is a 40 side elevation, partly in section, of a dumping receptacle embodying my invention; and Fig.

2 is a bottom plan view of the same, partly broken away.

In the drawing I have illustrated one embodiment of my invention and have shown the same as comprising an outer casing 1 which is preferably cylindrical in form and which has secured to the upper port? on thereof-a bail 2, here shown as abent barrigidly secured at its ends to the opposite sides of the casing. Mounted within this casing is a hopper 3, the upper edge of which is rigidly secured to the casing on a line spaced a considerable distance from the upper end of the casing, the hopper and the upper portion of the casing thus constituting the material receiving part of the structure. The lower end of the hopper terminates above the lower edge of the casing so that the latter constitutes a supporting skirt on which the structure as a whole may rest in an upright position. Preferably the lower edge of this supporting skirt is provided with a reinforcing band, such as the angleiron 4. The lower and smaller end of the hopper has a discharge opening 5 which is here shown as oblong in shape and is formed between downwardly extending flanges 6 which constitute the lower edges of the hopper. The flanges 6 at the ends of the opening are curved, as shown at 7, about an axis extending transversely to the hopper a considerable distance above the discharge opening. This opening is controlled by a laterally movable closure 8 which .is preferably in the form of a radlal gate, the body portion of which is curved to conform to the curvature of the lower edges of the hopper and the end portions of which are bent upwardly on the outer sides of the hopper, as shown at 9, and have secured thereto arms or straps 10 which are pivotally mounted on studs 11 carried by the hopper, these studs being arranged substantlally at the axis about which the edges of the hopper i are curved, thus permitting the closure to l e close to the edges of the hopper and effectively close the discharge opening but to be swung laterally out of line with the discharge opening to the position shown in dotted lines in Fig. 1.

The operating mechanism for thls laterally movable closure may take various forms but preferably comprises a lever mounted on the lower portion of the skirt of the outer casing and having operative connectlon with the closure. In the form here shown a lever 12 is pivotally mounted at13 between lugs 14 rigidly secured to the outer s de of the casing near the bottom thereof. R gidly secured to the lever, adjacent to its {1X15 and preferably formed integral therewith, is an inwardly extending arm 15, the skirt of the casing bein provided with an opening 16 through whlch the arm extends. Pivotally connected with the inner end of the arm 15 considerably less than the len h of the lever 12, it being here shown as :1 out one-third of the length of the lever. Consequentlythe power up lied to the lever, when transmitted to the links 17 will be multiplied and a relatively great power applied to the closure to move the same from beneath the material resting thereon. In the preferred arrangement the lever 12 extends normally upwardly alongside of and close to the outer side of the casing so that it is out of the way and does not in any way interfere with the. manipulation of the receptacle. When in thls position the arm 15 extends at-substantially ri ht angles thereto and the links 18 are in substantial alinement with the arm 15;. The

arm and the links thus constitute a toggle which, when the closure is in its closed position, will retain the same against outward movement but which when broken by the outward and downward movement of the lever will exert a powerful outward and upward pull on the closure, thus moving the same to its open position, as shown 1n dotted lines in Fig. 1. The links 17 are preferably angular so that their central portions are slightly lower than their end port-ons to permit the same to clear the edge of the closure at an intermediate point of movement. lhe lower end of the hopper and the closure are spaced such a distance above the lower edge 1 of the casing that the closure and its operating mechanism will, in all positions thereof, be above the lower edge of the casing. The skirt of the casing may also be provided w th openingsQO spaced circumferentially about the same to provide hand grips, whereby a workman'inay grasp the receptacle, when the latter is suspended from the cable, to properly position the same for dumping.

While I have shown and described one embodiment of my invention Iwish it to be understood that I do not desire to be l mited I spaced from the top thereof and having its lower end above the lower edge of the casing and provided with a discharge opening, a

swinging closure for said discharge opening,

a lever mounted on said casing and arranged normally alongside of and close to the same,

and a toggle having one arm rigidly secured to said lever and having its other arm pivotally connected with said closure.

2. In a dumping receptacle, a casing, a

hopper arranged within said casing, having its upper end secured to said casin on a line spaced from the top thereof and having its lower end above the lower edge of said casing and provided with a discharge opening, the lower edges of said hopper at opposite sides of said discharge opening being curved about an axis transverse to said hopper, a curved closure for said opening, means for pivotally supporting said closure at the axis of said curved edges, a lever mounted on said casing near the bottom thereof and extending upwardly alongside of said casing, and a toggle having one arm rigidly connected with said lever and havin its other arm pivotally connected with said. closure.

3. In a dumping receptacle, a casing, a hopper arranged within said casing, having its upper end securedto said casin on a lme spaced from the top thereof and aving its lower end above the lower edge 'of said casing and provided with a discharge opening, a swinging closure for said discharge opening a lever mounted on said casing and arranged normally alongside of and close to the same, an inwardly extending arm connected with said lever, and means for connecting said arm with said closure, said casin having near its lower end circumferentiall holes.

4. A dumping receptacle comprising a hop-.
